Dust from the dry Puna Plateau in northwestern Argentina was an important source of iron for the nutrient-deficient South Pacific in the last two glacial cycles—especially at the beginning of these cycles. This was the key finding of a study presented in the Proceedings of the National Academy of Sciences journal by a team of researchers led by geochemist Dr. Torben Struve from the University of Oldenburg.
